+
+TF-A performs a full initialization of Secure peripherals and installs a
+secure monitor (BL32=SPMin).
+
+U-Boot is running in normal world and uses TF-A monitor to access
+to secure resources.
+
+The **Trusted** boot chain with **OP-TEE**

+    +-------------+-------------------------+------------+-------+
+
+TF-A performs a full initialization of Secure peripherals and installs OP-TEE
+from specific partitions (teeh, teed, teex).
+
+U-Boot is running in normal world and uses OP-TEE monitor to access
+to secure resources.

+    +-------------+------------+------------+-------+
+
+SPL has limited security initialization
+
+U-Boot is running in secure mode and provide a secure monitor to the kernel
+with only PSCI support (Power State Coordination Interface defined by ARM).
+
+All the STM32MP15x boards supported by U-Boot use the same generic board
+stm32mp1 which support all the bootable devices.
+
+Each board is configured only with the associated device tree.
+
+Device Tree Selection
+---------------------
+
+You need to select the appropriate device tree for your board,
+the supported device trees for STM32MP15x are:
+
++ ev1: eval board with pmic stpmic1 (ev1 = mother board + daughter ed1)
+
+   + stm32mp157c-ev1
+
++ ed1: daughter board with pmic stpmic1
+
+   + stm32mp157c-ed1
+
++ dk1: Discovery board
+
+   + stm32mp157a-dk1
+
++ dk2: Discovery board = dk1 with a BT/WiFI combo and a DSI panel
+
+   + stm32mp157c-dk2
+
++ avenger96: Avenger96 board from Arrow Electronics
+
+   + stm32mp157a-avenger96
+
+Build Procedure
+---------------
+
+1. Install the required tools for U-Boot
+
+   * install package needed in U-Boot makefile
+     (libssl-dev, swig, libpython-dev...)
+
+   * install ARMv7 toolchain for 32bit Cortex-A (from Linaro,
+     from SDK for STM32MP15x, or any crosstoolchains from your distribution)
+     (you can use any gcc cross compiler compatible with U-Boot)
+
+2. Set the cross compiler::
+
+    # export CROSS_COMPILE=/path/to/toolchain/arm-linux-gnueabi-
+
+3. Select the output directory (optional)::
+
+   # export KBUILD_OUTPUT=/path/to/output
+
+   for example: use one output directory for each configuration::
+
+   # export KBUILD_OUTPUT=stm32mp15_trusted
+   # export KBUILD_OUTPUT=stm32mp15_optee
+   # export KBUILD_OUTPUT=stm32mp15_basic
+
+   you can build outside of code directory::
+
+   # export KBUILD_OUTPUT=../build/stm32mp15_trusted
+
+4. Configure U-Boot::
+
+   # make <defconfig_file>
+
+   with <defconfig_file>:
+
+   - For **trusted** boot mode : **stm32mp15_trusted_defconfig**
+   - For **trusted** with OP-TEE boot mode : **stm32mp15_optee_defconfig**
+   - For basic boot mode: stm32mp15_basic_defconfig
+
+5. Configure the device-tree and build the U-Boot image::
+
+   # make DEVICE_TREE=<name> all
+
+   Examples:
+
+  a) trusted boot on ev1::
+
+     # export KBUILD_OUTPUT=stm32mp15_trusted
+     # make stm32mp15_trusted_defconfig
+     # make DEVICE_TREE=stm32mp157c-ev1 all
+
+  b) trusted with OP-TEE boot on dk2::
+
+      # export KBUILD_OUTPUT=stm32mp15_optee
+      # make stm32mp15_optee_defconfig
+      # make DEVICE_TREE=stm32mp157c-dk2 all
+
+  c) basic boot on ev1::
+
+      # export KBUILD_OUTPUT=stm32mp15_basic
+      # make stm32mp15_basic_defconfig
+      # make DEVICE_TREE=stm32mp157c-ev1 all
+
+  d) basic boot on ed1::
+
+      # export KBUILD_OUTPUT=stm32mp15_basic
+      # make stm32mp15_basic_defconfig
+      # make DEVICE_TREE=stm32mp157c-ed1 all
+
+  e) basic boot on dk1::
+
+     # export KBUILD_OUTPUT=stm32mp15_basic
+     # make stm32mp15_basic_defconfig
+     # make DEVICE_TREE=stm32mp157a-dk1 all
+
+  f) basic boot on avenger96::
+
+     # export KBUILD_OUTPUT=stm32mp15_basic
+     # make stm32mp15_basic_defconfig
+     # make DEVICE_TREE=stm32mp157a-avenger96 all
+
+6. Output files
+
+   BootRom and TF-A expect binaries with STM32 image header
+   SPL expects file with U-Boot uImage header
+
+   So in the output directory (selected by KBUILD_OUTPUT),
+   you can found the needed files:
+
+  - For **Trusted** boot (with or without OP-TEE)
+
+     - FSBL = **tf-a.stm32** (provided by TF-A compilation)
+     - SSBL = **u-boot.stm32**
+
+  - For Basic boot
+
+     - FSBL = spl/u-boot-spl.stm32
+     - SSBL = u-boot.img
+
+Switch Setting for Boot Mode
+----------------------------
+
+You can select the boot mode, on the board with one switch, to select
+the boot pin values = BOOT0, BOOT1, BOOT2
+
+  +-------------+---------+---------+---------+
+  |*Boot Mode*  | *BOOT2* | *BOOT1* | *BOOT0* |
+  +=============+=========+=========+=========+
+  | Recovery    |  0      |  0      |  0      |
+  +-------------+---------+---------+---------+
+  | NOR         |  0      |  0      |  1      |
+  +-------------+---------+---------+---------+
+  | eMMC        |  0      |  1      |  0      |
+  +-------------+---------+---------+---------+
+  | NAND        |  0      |  1      |  1      |
+  +-------------+---------+---------+---------+
+  | Reserved    |  1      |  0      |  0      |
+  +-------------+---------+---------+---------+
+  | SD-Card     |  1      |  0      |  1      |
+  +-------------+---------+---------+---------+
+  | Recovery    |  1      |  1      |  0      |
+  +-------------+---------+---------+---------+
+  | SPI-NAND    |  1      |  1      |  1      |
+  +-------------+---------+---------+---------+
+
+- on the **daugther board ed1 = MB1263** with the switch SW1
+- on **Avenger96** with switch S3 (NOR and SPI-NAND are not applicable)
+- on board **DK1/DK2** with the switch SW1 = BOOT0, BOOT2
+  with only 2 pins available (BOOT1 is forced to 0 and NOR not supported),
+  the possible value becomes:
+
+    +-------------+---------+---------+
+    |*Boot Mode*  | *BOOT2* | *BOOT0* |
+    +=============+=========+=========+
+    | Recovery    |  0      |  0      |
+    +-------------+---------+---------+
+    | NOR     (NA)|  0      |  1      |
+    +-------------+---------+---------+
+    | Reserved    |  1      |  0      |
+    +-------------+---------+---------+
+    | SD-Card     |  1      |  1      |
+    +-------------+---------+---------+
+
+Recovery is a boot from serial link (UART/USB) and it is used with
+STM32CubeProgrammer tool to load executable in RAM and to update the flash
+devices available on the board (NOR/NAND/eMMC/SD card).
+
+The communication between HOST and board is based on
+
+  - for UARTs : the uart protocol used with all MCU STM32
+  - for USB : based on USB DFU 1.1 (without the ST extensions used on MCU STM32)
+
+Prepare an SD card
+------------------
+
+The minimal requirements for STMP32MP15x boot up to U-Boot are:
+
+- GPT partitioning (with gdisk or with sgdisk)
+- 2 fsbl partitions, named fsbl1 and fsbl2, size at least 256KiB
+- one ssbl partition for U-Boot
+
+Then the minimal GPT partition is:
+
+  +-------+--------+---------+-------------+
+  | *Num* | *Name* | *Size*  | *Content*   |
+  +=======+========+=========+=============+
+  | 1     | fsbl1  | 256 KiB | TF-A or SPL |
+  +-------+--------+---------+-------------+
+  | 2     | fsbl2  | 256 KiB | TF-A or SPL |
+  +-------+--------+---------+-------------+
+  | 3     | ssbl   | enought | U-Boot      |
+  +-------+--------+---------+-------------+
+  | 4     | <any>  | <any>   | Rootfs      |
+  +-------+--------+---------+-------------+
+
+Add a 4th partition (Rootfs) marked bootable with a file extlinux.conf
+following the Generic Distribution feature (doc/README.distro for use).
+
+According the used card reader select the correct block device
+(for example /dev/sdx or /dev/mmcblk0).
+
+In the next example, it is /dev/mmcblk0
+
+For example: with gpt table with 128 entries
+
+a) remove previous formatting::
+
+     # sgdisk -o /dev/<SD card dev>
+
+b) create minimal image::
+
+    # sgdisk --resize-table=128 -a 1 \
+    -n 1:34:545		-c 1:fsbl1 \
+    -n 2:546:1057		-c 2:fsbl2 \
+    -n 3:1058:5153		-c 3:ssbl \
+    -n 4:5154:		    -c 4:rootfs \
+    -p /dev/<SD card dev>
+
+  With other partition for kernel one partition rootfs for kernel.
+
+c) copy the FSBL (2 times) and SSBL file on the correct partition.
+   in this example in partition 1 to 3
+
+   for basic boot mode : <SD card dev> = /dev/mmcblk0::
+
+    # dd if=u-boot-spl.stm32 of=/dev/mmcblk0p1
+    # dd if=u-boot-spl.stm32 of=/dev/mmcblk0p2
+    # dd if=u-boot.img of=/dev/mmcblk0p3
+
+   for trusted boot mode: ::
+
+    # dd if=tf-a.stm32 of=/dev/mmcblk0p1
+    # dd if=tf-a.stm32 of=/dev/mmcblk0p2
+    # dd if=u-boot.stm32 of=/dev/mmcblk0p3
+
+To boot from SD card, select BootPinMode = 1 0 1 and reset.
+
+Prepare eMMC
+------------
+
+You can use U-Boot to copy binary in eMMC.
+
+In the next example, you need to boot from SD card and the images
+(u-boot-spl.stm32, u-boot.img) are presents on SD card (mmc 0)
+in ext4 partition 4 (bootfs).
+
+To boot from SD card, select BootPinMode = 1 0 1 and reset.
+
+Then you update the eMMC with the next U-Boot command :
+
+a) prepare GPT on eMMC,
+   example with 2 partitions, bootfs and roots::
+
+    # setenv emmc_part "name=ssbl,size=2MiB;name=bootfs,type=linux,bootable,size=64MiB;name=rootfs,type=linux,size=512"
+    # gpt write mmc 1 ${emmc_part}
+
+b) copy SPL on eMMC on firts boot partition
+   (SPL max size is 256kB, with LBA 512, 0x200)::
+
+    # ext4load mmc 0:4 0xC0000000 u-boot-spl.stm32
+    # mmc dev 1
+    # mmc partconf 1 1 1 1
+    # mmc write ${fileaddr} 0 200
+    # mmc partconf 1 1 1 0
+
+c) copy U-Boot in first GPT partition of eMMC::
+
+    # ext4load mmc 0:4 0xC0000000 u-boo	t.img
+    # mmc dev 1
+    # part start mmc 1 1 partstart
+    # mmc write ${fileaddr} ${partstart} ${filesize}
+
+To boot from eMMC, select BootPinMode = 0 1 0 and reset.
+
+MAC Address
+-----------
+
+Please read doc/README.enetaddr for the implementation guidelines for mac id
+usage. Basically, environment has precedence over board specific storage.
+
+For STMicroelectonics board, it is retrieved in STM32MP15x OTP :
+
+ - OTP_57[31:0] = MAC_ADDR[31:0]
+ - OTP_58[15:0] = MAC_ADDR[47:32]
+
+To program a MAC address on virgin OTP words above, you can use the fuse command
+on bank 0 to access to internal OTP:
+
+Prerequisite: check if a MAC address isn't yet programmed in OTP
+
+1) check OTP: their value must be equal to 0
+
+   STM32MP> fuse sense 0 57 2
+   Sensing bank 0:
+   Word 0x00000039: 00000000 00000000
+
+2) check environment variable
+
+   STM32MP> env print ethaddr
+   ## Error: "ethaddr" not defined
+
+Example to set mac address "12:34:56:78:9a:bc"
+
+1) Write OTP::
+
+    STM32MP> fuse prog -y 0 57 0x78563412 0x0000bc9a
+
+2) Read OTP::
+
+    STM32MP> fuse sense 0 57 2
+    Sensing bank 0:
+    Word 0x00000039: 78563412 0000bc9a
+
+3) next REBOOT, in the trace::
+
+    ### Setting environment from OTP MAC address = "12:34:56:78:9a:bc"
+
+4) check env update::
+
+    STM32MP> env print ethaddr
+    ethaddr=12:34:56:78:9a:bc
+
+.. warning:: This command can't be executed twice on the same board as
+             OTP are protected. It is already done for the board
+             provided by STMicroelectronics.
+
+Coprocessor firmware
+--------------------
+
+U-Boot can boot the coprocessor before the kernel (coprocessor early boot).
+
+a) Manuallly by using rproc commands (update the bootcmd)
+
+   Configurations::
+
+	# env set name_copro "rproc-m4-fw.elf"
+	# env set dev_copro 0
+	# env set loadaddr_copro 0xC1000000
+
+   Load binary from bootfs partition (number 4) on SD card (mmc 0)::
+
+	# ext4load mmc 0:4 ${loadaddr_copro} ${name_copro}
+
+   => ${filesize} variable is updated with the size of the loaded file.
+
+   Start M4 firmware with remote proc command::
+
+	# rproc init
+	# rproc load ${dev_copro} ${loadaddr_copro} ${filesize}
+	# rproc start ${dev_copro}"00270033
+
+b) Automatically by using FIT feature and generic DISTRO bootcmd
+
+   see examples in the board stm32mp1 directory: fit_copro_kernel_dtb.its
+
+   Generate FIT including kernel + device tree + M4 firmware with cfg with M4 boot::
+
+   $> mkimage -f fit_copro_kernel_dtb.its fit_copro_kernel_dtb.itb
+
+   Then using DISTRO configuration file: see extlinux.conf to select the correct
+   configuration:
+
+   - stm32mp157c-ev1-m4
+   - stm32mp157c-dk2-m4
+
+DFU support
+-----------
+
+The DFU is supported on ST board.
+
+The env variable dfu_alt_info is automatically build, and all
+the memory present on the ST boards are exported.
+
+The dfu mode is started by the command::
+
+  STM32MP> dfu 0
+
+On EV1 board, booting from SD card, without OP-TEE::
+
+  STM32MP> dfu 0 list
+  DFU alt settings list:
+  dev: RAM alt: 0 name: uImage layout: RAM_ADDR
